Abstract
The present invention provides a diagnostic method comprising continuously monitoring and transmitting urine output and urine flow rates of a catheterized patient to means which correlate the same with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR.
Claims17
A diagnostic method comprising:
- connecting a catheter of a catheterized patient to a low flow metering device, wherein said low flow metering device incorporates a drop generator and a droplet counter, continuously monitoring urine output and urine flow rates of said catheterized patient by measuring real time minute fluctations in renal flow and renal output by measuring drops of urine by said drop generator and droplet counter;
- transmitting said real time minute fluctations in renal flow and renal output to means which calculate a change of urine output per minute units to correlate with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR;
- and graphically displaying through a display said minute fluctations in renal flow and renal output, wherein calculating said change of urine output per minute units comprises calculating a slope.
A diagnostic method comprising:
- connecting a catheter of a catheterized patient to a low flow metering device, wherein said low flow metering device incorporates a drop generator and a droplet counter, continuously monitoring urine output and urine flow rates of said catheterized patient by measuring real time minute fluctations in renal flow and renal output by measuring drops of urine by said drop generator and droplet counter;
- transmitting said real time minute fluctations in renal flow and renal output to means which calculate a change of urine output per minute units to correlate with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR;
- and graphically displaying through a display said minute fluctations in renal flow and renal output for determining the hemodynamic state of a patient, further comprising administering a bolus of fluid to the patient and monitoring and displaying urine flow reaction to said bolus to determine the state of hydration and hemorrhagic shock.
A diagnostic method which comprises continuous monitoring and measuring of urine output and urine flow of a catheterized patient which method includes linking the output of said device with means which correlate a slope of urine output per minute units with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR.
A system for management of a hemodynamic state and kidney function of a body comprising a low flow metering device connected to a catheter inserted into the body by measuring real time minute fluctations in renal flow and renal output by measuring drops of urine by said drop generator and droplet counter;
- wherein said low flow metering device transmits said real time minute fluctations in renal flow and renal output to monitoring means which calculate a slope of urine output per minute units and to displaying means which display the slope of urine output and urine flow rates per minute units, further comprising means which correlate the slope of urine output per minute units with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR.
